Trend hit by UPX vulnerability
Compression handling issue affects swathe of products.
A wide range of Trend Micro security products are affected by a flaw in the handling of files compressed with
UPX, which could be exploited to shut down the product or even access a machine remotely. An update is available to
circumvent the problem.
The buffer overflow vulnerability was pointed out to Trend in mid-January, and has now been disclosed
following the release of a pattern file to fix the hole. Affected products include flagship OfficeScan and
PC-cillin scanners, as well as various mail and network security products including Linux and NetWare
offerings.
Trend's announcement of the problem, along with the fix, is available
here. An alert from
iDefense is here, and
another from Secunia here.
A second and less significant vulnerability, exploitable only from the local system, has also been reported in the
Anti-Rootkit module included in several Trend products. This flaw has also been fixed with an upgrade, and
details are again available from
Trend,
iDefense or
Secunia. Trend users are advised to ensure both fixes
are applied as soon as possible.
